Did Bismarck prove that aircraft had taken control of the sea?
Short answerIt showed that air power had become an important component of sea control, rather than proving ships no longer mattered.
NotesBismarck's loss does not prove that control of the sea had passed entirely to aircraft. Air reconnaissance helped find the battleship, and a torpedo attack slowed her. Those actions made the later interception possible while surface forces still completed the operation. Control of the air had become one component of control of the sea. The episode therefore supports integration of air and naval power rather than a simple succession from one to the other.
